Ceramic fuses are items used in electrical systems to protect against excessive currents and surges that can cause damage or fire. They are a cylindrical body of different diameter and length made of ceramics, in which electric wires wrapped with metal wire or foil are installed. When the current exceeds normal values, the ceramic fuse will melt or burn, cutting off the electrical current and protecting the connected devices. They can be installed in fixed fuses or in modular circuit protection systems.
Ceramic fuses can be different in size and characteristics, such as the magnitude of the current or voltage, as well as in the type of installation to meet the specific requirements of the electrical system. They can be used through special sockets or housings as well as by embedding in electrical devices. They are used in a wide range of applications, including automotive, industrial and home electronics, as well as power electrical systems and appliances. Ceramic fuses, also called fusible, are extremely important in the construction of various electrical systems and devices and not only create prerequisites for safety, but also extend the life of various electrical appliances and protect them from damage in the event of problems in the electrical network.
These fuses are used in various fields such as industry, automotive and domestic electrical installations. They provide security and protection to electrical systems and help prevent fires and other accidents. The large choice of shape and size helps the high spectrum of application and are an important component both for consumer systems with voltages from 200 VAC to 400 VAC, but are the basis for building solar photovoltaic systems with more than 1000 VDC.
